An audience of one is a lot for a jazz guy such as myself.
Kinda. We didn't have a roof:
I played a house party at "Sunny Side Trailer Park" Clearwater, FL sometime in the 90s inside a mobile home. It got out of hand to the point where the guy took a sawzall and cut the back wall off of it to "make more room". The bonfire going out back got out of hand so the cops showed up and it was party over. With the back of the trailer cut out. Hilarious.Reminds me of the recent Super Bowl halftime show trailers. Have played on a trailer, never at a trailer park.
